ZN23-40.5 MV vacuum circuit breaker waa gudaha qalabka qaybinta MV saddex-waji AC 50Hz, danab lagu qiimeeyay 40.5kV, waxaa lagu beegi karaa JYN35/GBC-35 nooca switchcabinet.Suitablefor kontoroolka iyo ilaalinta in warshad korontada, substation iyo nidaamka qaybinta korontada, gaar ahaan ku haboon goobaha shaqada ee soo noqnoqda
Nala Soo Xidhiidh
● ZN23-40.5 MV vacuum circuit breaker waa indoor MV qalab qaybinta saddex-waji AC 50Hz, danab lagu qiimeeyay 40.5kV, waxaa la mid ah karaa JYN35/GBC-35 nooca beddelka golaha. Ku habboon xakamaynta iyo ilaalinta warshadda korantada, substation iyo nidaamka qaybinta korantada, gaar ahaan ku habboon meelaha joogtada ah ee hawlgalka. Wareegtada faakuumka waa nooca gaadhi-gacmeed, oo leh qaab-dhismeed macquul ah, dayactir ku habboon, ammaan iyo adeegsi la isku halayn karo.
1. Heerkulka deegaanka: xadka sare +40 ℃, xadka hoose -15℃ (aagga qabow -25℃);
2. Joog: aan ka badnayn 2000m;
3. Qoyaanka qaraabada: celceliska qiimaha maalin kasta kama badna 95%, celceliska bishiiba kama badna 90%;
4. Cadaadiska uumiga oo buuxa: celceliska qiimaha maalinlaha ah kama sarreeyo 2.2 × 10 -3 Mpa, celceliska bishii kama sarreeyo 1.8×10-3 Mpa;
5. Xoogga dhulgariirka kama badna 8 darajo;
6. Ma jiro dab, qarax, wasakh, daxal kiimiko iyo meel gariir daran.
1. Guud ahaan qaab-dhismeedka wareeggu waa nooca gaadhi-gacan, isticmaal CT19 ama CD10 farsamaynta, waxa loo qaybin karaa JYN1 iyo GBC laba nooc oo qaab dhismeed ah.
2. Jirka jebiya wareegga waxa uu ka kooban yahay jir, dahaye, vacuum interrupter, dunta iyo dhaqaaqa iyo garabka taagan. Dusha hoose ee jirku wuxuu ku qalabaysan yahay 4 taayirrada, loogu talagalay dhaqdhaqaaqa wareegga wareegga, iwm. Wareegga wareegga wuxuu leeyahay sifooyin mug yar, qaab dhismeedka fudud, nolosha adeegga dheer, dayactirka fudud, khatarta qarax, ma wasakhaysan iwm.
Wareegtada wareegtadu waxay ku qalabaysan tahay dhexda xidhidhiyaha dhaadheer ee magnetic field vacuum interrupter, marka firfircoonida, xidhiidhka joogtada ah ee carqaladeeyaha faakuumka la kala saaro, farqiga xidhiidhka ayaa soo saari doona vacuum arc oo damin doona marka hadda uu eber ka sarreeyo. Sababtoo ah qaab dhismeedka gaarka ah ee xiriirka, farqiga xiriirku wuxuu soo saari doonaa goobta magnetic dhererka ku habboon inta lagu jiro arc xiriirka, arc si siman loo qaybiyay dusha sare ee xiriirka, ilaalinta korantada yar ee arc, si ay u yareyso xawaaraha daxalka korantada iyo qolka qaansada oo leh sare. xoogga soo kabashada warbaahinta arc, hagaajinta wareegga wareegga jebinta awoodda wareegga gaaban iyo nolosha korontada.
